Class: Life Science Unit: Environment- Pond Water Testing Project Topic: Analyzing the Test Kits Results
Instructional Activities: Students should be able to:
1. Assess the water quality of a sample through chemical means 2. Assess the environmental quality of a water sample based on the presence of certain organisms 3. Be able to explain that all living things are affected by the environment 4. Analyze data/information for meaning 5. Distinguish between observations that support a hypothesis and those that do not
Time & Activity
9:15-9:20A.M. Inform the class that they will be using the information collected from the water quality tests and the macroinvertebrates they found in the water sample to make a general determination about the quality of the water in the sampling area.
9:20-9:50 Distribute student worksheets.
Using the results found from the last activity, students will complete the required sections on their worksheets. They will need to reference the Water Sampling Fieldbook to determine whether or not the Test Kit results fall into the acceptable range for good quality.
9:50-10:10 Review of completed worksheets. Class discussion.
Assignment: 1. (Comprehension) Are any of your results not what you expected them to be? Which ones? Explain your reasoning. 2. (Analysis) Is there a relationship between Dissolved Oxygen levels and the types of plants, animal, or other organisms you observed in the water? If so, describe the relationship. 3. (Evaluation) Do you think that your water source is a good environment for organisms to survive based on pH levels? Why or why not? 4. (Analysis) How did the Dissolved Oxygen level of your water sample compare to the temperature? Did you see any relationship between the two? If so, what was it?
Activity materials needed:
